  • the invention is based on the further object of using a metal halide lamp high color rendering and increased light output operate so that their Brennlage no restriction is subject. At most there should be a small difference the operating data between horizontal and vertical burning position result.
  • Another object is to provide an electronic ballast that perform an automated procedure as possible to impose an appropriate Amplitude modulation with AM degree AMI near a longitudinal acoustic Resonance for different focal positions approximately the same color rendering and to achieve luminous efficacy.
  • Another object is a sought acoustic resonance, preferably the second longitudinal, reliable in any burning position.

  • the operating method according to the invention is geared to this, from the outset always a certain frequency, preferably near the second longitudinal Resonance of the horizontal burning position, to stimulate continuous use, because with it optimal mixing of the filling components, especially the metal halides, can also be achieved in non-horizontal burning position. Thus, color effects and color scattering largely avoided.
  • This frequency must be delayed after Maintaining a certain grace period will be imprinted on the system.
  • This approach allows a reliable swing close to the optimum Resonance, in particular the second longitudinal acoustic resonance f002 of horizontal burning position.
  • the process is mainly in ceramic high-pressure lamps suitable with an aspect ratio (length: diameter) of at least 1.5, preferably ⁇ 2 (typically 3 to 6). It uses an HF sweep operation, which means the segregation is suppressed and the mixing of the metal halide arc plasma is improved.
  • the location of the resonance f002 in horizontal burning position is for an individual Lamp determined first. This can be done in advance through various procedures or again on-line in the operation of the lamp done, z. B. by measuring the Lamp impedance during operation with rectangular current impression and superimposed sinusoidal signal, for example, the amplitude of the sinusoidal component about 5-15% of the current amplitude with variation of the frequency of the sine wave signal should be.

  • the inside length represents that dimension the lamp that defines the second longitudinal acoustic resonance, which for optimal mixing of the arc plasma, especially in vertical Burning position, needs to be stimulated.
  • the geometry is cylindrical with straight or bevelled ends, but also bulbous vessels are suitable. In such cases, instead of a geometrically determined inside length, an effective Inner length can be assumed.

  • This basic current signal form becomes, possibly after a waiting period (Warming up the lamp), also an amplitude modulation AM imprinted, whose fundamental frequency is the second longitudinal resonance f002hor in horizontal Burning position is. this fundamental frequency is the starting point of the control.
  • the frequency fSW can be in the range of the first azimuthal and radial resonance f100 and f010 are chosen, preferably near their mean with a deviation up to to 10%, ie 10% x (f100 + f010) / 2).
  • Prerequisite for a procedure for setting the AM frequency for optimal Mixing of the arc plasma in each burning position is first the determination and storing the location of the second longitudinal resonance frequency f002 in FIG practically always already mixed horizontal burning position.
  • To set a Basic operation with this frequency must first individually for each lamp

  • the AM degree is set to 15 to 30%.
  • P refers while the amplitude modulation is about 15-25% amplitude modulation set.
  • the fundamental solution consists in the controlled recognition of the optimal frequency point fopt of the AM and the appropriate signal level AMI of the AM degree for the mixing of the metal halide plasma one by means of acoustic longitudinal Resonance controlled metal halide discharge lamp and the provision an electronic ballast for operation in optimally mixed Mode.
  • the AM degree is a measure of the respective electrical power, based on the total power, which is converted into the excitation of longitudinal resonances.
  • the behavior of the lamp impedance Z (fAM) as a function of the frequency fAM over the frequency range ⁇ F is recorded as a function of the AM degree and saved as a characteristic field. It shows up with an increase in the AM degree first one and then two, and even several consecutive as a function of fAM dynamic extremema of the lamp impedance, which in the course of the Gradually increasing and increasing the degree of AM education.

Preference is given to safety a larger frequency window between the frequency start point ST and the frequency end point SP, because at the end point SP no significant plasma mixing, or at the upper frequency point ST possibly a small plasma mixture is present.
  • the procedure described uses the with increasing frequency shift gradually improved mixing of the metal halides in the plasma to characteristic Frequencies, ie in particular the resonance frequency f002, for the mixing process to investigate. It turns out that preferably a constant rate of Frequency shift (frequency scan) should be chosen, taking care of it Find an optimal speed in the order of 0.1 to 0.5 kHz / sec leaves the normal lamp operation.
